"Mr Iauko maintains he was elected as the president of the Vanua'aku Pati after the annual congress of the country's oldest and biggest political party early last month. Mr Natapei disputes this and last week filed an action with the Supreme Court calling in part for Mr Iauko's election to be declared null and void. Our correspondent in Port Vila says at this morning's session Mr Iauko took a seat on the opposition benches. He says Mr Iauko's recent appointment as deputy leader of the opposition caused further confusion. The parliamentary speaker has called on both men to clarify who holds the Vanuaaku Party leadership role, but this may have to wait for a court ruling. No date has yet been set for the proceedings."
